Barium Carbonate

£3.30 – £52.15exc. Vat

Code 3002 Barium Carbonate. BaCO3. Used in casting slips at low levels to prevent scumming (up to 0.5%). Used in high temperature glazes as a flux and produces matt and semi-matt surfaces at earthenware temperatures. At higher temperatures it can make a distinctive turquoise with copper. In bodies it seems to impart better translucency but can lead to weakness and excessive shrinkage.
